Alabama's top paid tourist attraction is searching for new Space Camp crew trainers in Huntsville.

The U.S. Space & Rocket Center will host a job fair from 10 a.m. to 4 p.m. today to recruit potential trainers for the program. Applicants must be at least 20 years old, have 30 hours of college credit and three professional references.

Candidates who have worked with children at least one year are preferred, as crew trainers supervise camp attendees primarily 9-18 years old.

"Crew trainers guide participants through the history and future of spaceflight, astronaut simulators and simulated space missions," a news release said. "They also organize, plan and carry out educational activities designed to ensure trainees receive a quality camp experience that aligns with the Rocket Center's mission of being a world-class educational facility."

Free on-site housing and meals are available to resident crew trainers.
